If you have a look at the satellite image above, one of the tropical waves is expected to develop, with the NHC giving it a 50% chance of developing within the next 48 hours.
Beside it to the east is another apparent tropical wave just emerging from Africa. The NHC hasn't given this an 'invest' status just yet (meaning they aren't considering it likely to develop within the next 48 hours) but the NHC generally takes a while to officially acknowledge new tropical waves as potential cyclones.
Question is, will this wave ultimately be absorbed by the current invest wave (94L, I think) which is the 50% one? Or is it far enough away that it might develop as a separate tropical wave?
(This might seem like a newbish question but I've seen tropical waves appear to 'merge' before so I didn't want to be too sure of myself in considering this new one a distinct system in and of itself)
